APPARATUS FOR COVERING CYLINDERS WITH CARD FILLETS.

SFEGIFIGATION forming part of Letters Patent No. 429,985, dated June 10, 1890.

Application filed August l i, 1889. $erial No. 320,738. (No model.) Patented in England May 17, 1887, No. 7,168.

To all whom it may concern:

Be it known that we, NATHAN WHITLEY, FREDERICK WHITLEY THoMsoN, and HENRY HOYLE, subjects of the Queen of Great Britain and Ireland, and all residing at Halifax, in the county of York, England, have invented Improvements in Apparatus for Covering Cylinders with Card Fillets, (for which a British Patent, No. 7,158, of May 17, 1887, has been granted,) of which the following is a specification.

This invention relates to improved apparatus for the purpose aforesaid, and the object is to efiect such operation without exposing the fillet to an uneven or undue strain consequent on the use of apparatus as heretofore constructed, and also to indicate the degree of tension on the fillet during the operation of covering the cylinder, and to dispense with certain parts hitherto in use.

The apparatus for the purpose aforesaid, constructed according to this our said invention, consists of a carriage-plate operated or caused to traverse on a' bed by a screw. Upon the carriage-plate rests a platform. This platform is hinged to the carriage-plate at its back or edge nearest the cylinder to be covered. The platform carries a fixed or nonrotating barrel, around or partly around the circumference of which is a spiral rim or worm of pitch about equal to the width of the foundation of the widest fillet in ordinary use. The barrel is at a slight angle or oblique to the cylinder to be covered. Attached to the carriage-plate is a vertical stud passing through a hole in the platform, and on the stud are a spiral spring and adjusting lock-nuts, or lever and weights may be substituted for the spring. Abracket or arm attached to the barrel carriesa guide or trough having a movable cover or presser-plate, the pressure upon which is determined and regulated by an adjustable spring. To the platform is attached a stud, the projecting end of 5 which works in a slot or folk formed in the shorter arm of an L-lever, the upright arm of which is tapered and forms a pointer or index-finger, which works, for the purpose hereinafter described, along a radius-dial or 50 index-plate.

The operation is as follows: The end of the fillet is passed into the guide and therefrom spirally around the barrel until it reaches the cylinder to be covered, and to which its end is secured. The pressure-plate of the guide and the adjustable spring are then to be placed in position and adjusted. As the cylinder to be covered is caused to slowly revolve, the pressure-plate of the guide, together with the grip of the fillet on the barrel, puts tension on the fillet according to the pressure on the presser-plate indicated by the spring. The tension on the fillet tends to raise the platform on its hinges and against the spiral spring or weighted lever, if used, and as the finger forming part of the L-lever is centered on the support of the radius-dial or index-plate just in proportion to the lift of the platform, so will the longer or upright arm of the L-lever indicate on the radius-plate the amount of tension on the fillet, and to indicate or instantly give Warning of any material variation of tensile strain from that determined upon (arising from unseen causes) an electric bellmay be operated by contact of the index-pointer of the lever L, above referred to, with adjustable studs.

Such being the nature and object of this our said invention, the following is a complete description of the same, reference being had to the accompanying drawings.

Figure 1 is aside elevation of our improved apparatus. Fig. 2 is a plan View, on a reduced scale of Fig. 1, also showing the bearing-rest or slide-bed. Fig. 3 is a side elevation of the apparatus, partly in section,showing a portion of the cylinder to be covered, also the drivingear for imparting the requisite traversing motion of the improved apparatus. Figs. 4, 5, and '6 are details of parts of the apparatus shown detached. Figs. .5 and 5 show modifications of the device illustrated in Fig. 5. Fig. 7 is a plan view of the driving-gear.

At 1 is the carriage-plate, which is mounted o 5 upon a gantry or slide-bed 2, in which is the screw 3, gearing with a worm-wheel 4, by means of which the apparatus is traversed along thegantry 2 so as to lay the card-fillet 5 evenly upon the cylinder 6. The platform I00 9 is hinged at 8 to the carriage-plate 1.

At 10 is fixed a barrel, around or partly around the circumference of whichis a spiral rim or worm 11 of pitch about equal tothe width of the foundation of the widest fillet in ordinary use. The barrel 10 is at a slight angle to the cylinder 6 to be covered.

At 12 is a guide or trough, through which the fillet passes in its course to and around the barrel 10. The trough 12 is provided with a cover or presser-plate 13, which bears upon the card, and the pressure thereon is determined and regulated by the spiral spring 14 and adjusting-screw 15, carried by the stand ard and boss 16. The platform 9 has at its loose end a projecting stud 17, which works in the slot 18 of the L-lever 19, the upper end or point of which acts as an indicator on the radiusdial or index plate 20, whereby the strain or tension on the fillet 5 is indicated, because the barrel 10 is fast to the platform 9, and as the tension on the fillet 5 is greater or less so will the platform 9 be lifted on its hinge 8 more or less.

At 21 is a spiral spring, (or a lever and weight may be used,) which as the platform 9 rises is thereby forced upward and compressed against lock-nuts on the upper end of the spindle 22, and it is the yielding of the spring 21 which prevents undue strain being put upon the fillet during the winding on, the exact amount of tension on the fillet being indicated by the finger 19 on the radiusdial or index-plate 20. The same yielding pressure may be exerted upon the platform 9 by a weight 21 (see Fig. 53) mounted on one end of a lever 21, the outer end of which is curved or hooked to engage with a stud or projection on the platform 9; or the yielding pressure may be exerted by a weight 21, (see Fig. 5 suspended from the platform 9 by a hook 21 engaging with the stud on the platform.

At 23 is an electric battery connected to the bottom plate 1 by the wire 24. The opposite pole-wire is 25, the insulation being at 26.

At 00 y are two adjustable stops, Figs. 1 and 5. These stops are adjusted on the radiusdial 20, so that on the pointer 19 reaching either the circuit will be completed and a bell to rung, one stop as indicating when the maximum tension to be put on the fillet is reached, the other 11 warning the attendant should the tension from slipping or other cause he reduced below a desired limit.

The means by which the traversing screw 3 and worm-wheel1 are operated consist of the chain 29, driving the wheel 30 on the axis of the worm 3, the motion being taken from the gearing which actuates the axis 31 of the cylinder 6 through the intervention of the train of wheels shown at Fig. 7. The handle turns the pinion 31, gearing with the wheel 35, which drives the wheels 36 and 37 on the same stud or shaft 38. The wheel actuates the cylinder-shaft 31 by the wheel 39, and 37 actuates the wheel 40 and the chainwheel 41, which carries and imparts motion to the chain 29, (see also Fig. 1,) the gear being supported by the detachable frame 32 and temporarily applied to the carding-engine for the purpose of driving the improved apparatus for applying the card filleting to the cylinder 6, as described.

Ve would have it understood that we lay no claim to such gearing or to such bed or to the method of traversing the carriage.

\Ve claim as our invention 1. The improved apparatus comprising the barrel mounted upon the hinged platform, means for exerting an elastic or yielding pressure. upon the said platform, the dial and indicating-finger, an electric circuit controlled by the finger, and an electric bell in the circuit, all in combination for the purposes described.

2. The improved apparatus comprising the barrel mounted upon the hinged platform, means for exerting an elastic or yielding pressure upon the said platform, and a dial and indicating-finger, all in combination and substantially as described.

The improved apparatus comprising the barrel mounted upon the hinged platform, means for exerting an e astic or yielding pressure upon the said platform, an electric circuit, means for closing the circuit, and an electric bell or other indicator in the circuit controlled by the movement of the platform, all in combination and as described.

1. The barrel 10, mounted upon a hinged platform, in combination with means for exerting an elastic or yielding pressure upon the said plat-form, as described.
